Email Templates in ASP.NET

Till recently, whenever it was required to send an email, through a web application using SMTP, I would go ahead and use SMTPClient, a class provided by .NET Framework.All I needed to do for this, is to include namespace System.Net.Mail and I am ready to go.I would read the SMTP host IP, port number and timeout value from the configuration file and write a code snippet like below:

String hostIP=Convert.ToString(ConfigurationManager.AppSettings["SMTPHostIP"]);
Int16 portNumber = Convert.ToInt16(ConfigurationManager.AppSettings["SMTPPort"]);
Int32 timeout = Convert.ToInt32(ConfigurationManager.AppSettings["SMTPTimeout"]);
SmtpClient smtpClient = new SmtpClient();
smtpClient.Timeout = timeout;
smtpClient.Host =hostIP;
smtpClient.Port = portNumber;
My next steps are to instantiate MailMessage class provided under the same namespace and invoke Send method, as below:

MailMessage mailMessage = new MailMessage
(fromAddress
,toAddress
,subject
,messageText);
smtpClient.Send(mailMessage);
Now, if the message text is a simple text, the above works fine.But, often we need to build the message programitically by concatenating data with the mail text.One way is to use a StringBuilder class and build the message text.There is yet another way which can simplify the code.Using email templates provided by ASP.NET.

We can build mail templates using a class MailDefinition.MailDefinition class is provided under namespace System.Web.UI.WebControls.

MailDefinition mailTemplate = new MailDefinition();
mailTemplate.BodyFileName = "~/mail_templates/TransactionConfirmation.html";
TransactionConfirmation.html is an html file which defines the structure of the email message.To insert data into the mail,we need to create a dictionary object like below:
Dictionary mailData = new Dictionary();
mailData.Add("<% TransactionNumber%>", trans.TransactionNumber.ToString());
mailData.Add("<%CardNumber%>", card.CardNumber.ToString());
mailData.Add("<%BankName%>", card.BankName);

mailData.Add("<%CardHoldersName%>", card.CardHoldersName);
Next step is to create mail message.

MailMessage mailMessage = mailTemplate.CreateMailMessage
(toAddress,mailData,new LiteralControl());
mailMessage.IsBodyHtml = true;
mailMessage.Subject = subject
The third parameter in CreateMailMessage method above is the owner i.e. a System.Web.UI.Control that own this mail definition.An HTML Template can be defined as below:

<%trans.TransactionNumber%></span> </td> </tr> <tr> <td> <%card.CardHolderName%>,<br><br> This email confirms your transaction.
<html><head>
<title>Transaction Confirmation</title>
</head>
<body>
<table><tr><td align="center">
<span>Transaction Confirmation for 




   Following are the details:<br><br>
Card Number : <%card.CardNumber%><br>
Bank Name : <%card.BankName%><br>
</td>
</tr>
<tr>
<td>Thank You
</td>
</tr>
</table>
</body>
</html>

Now isn't that cool.Happy Coding...

Technical Interview Screen





















  Which is better - singly linked list or doubly linked list? What are the pros and cons of using each? In a  Singly Linked List each node has pointer just to the next node and hence can be  traversed  in only one direction whereas in a Doubly Linked List, each node has pointers  to both previous and next nodes , hence can be traversed in both  directions.While this kind of traversal makes deletion of nodes easier  from a doubly linked list , because we now don’t have to traverse from  head and keep track of previous node but it consumes more memory since  it now has to store two pointers as compared to one in case of Singly Linked List.    function remove_node_singlyLinkedList(head, node)     tempnode = head     while (tempnode->next != node)         tempnode = tempnode->next     tempnode->next = node->next end function            Time Complexity - O(N)   function remove_node_doublyLinkedList(node)     node->prev->next = node->next     node->next->prev = nod

Natural Face Pack





















 All my life I have been using regular face packs readily available in drug stores and online store. The results are great but a slight problem. They contain a lot of chemicals that may not harm you right away but slow exposure to some of these carcinogens can impact your health. Some of us may live longer with no health issues but for some of us exposure to these chemicals can cause some gene mutations and that could lead to some serious health issues. Hence since last few years of my life I have been doing my by best to remove exposure to chemicals from my day to day life. That includes perfume, deodorants, make up stuff and hair dyes.Of all these I miss the hair dye the most because I loved experimenting with my hair color. Also miss my Channel perfume, I simply loved its subtle but intriguing fragrance.   Past few days my face was looking dull and full of wrinkles. So I missed my face packs and face peels. I was online searching for some natural options when I bumped into Apsara sk

Yesterday, I got Sky Drive and Google Drive clients installed on my laptop and things look pretty cool !                          I now have 2 GB (Drop Box) + 5 GB (Google Drive) + 7 GB (Sky Drive) = 14 GB of could storage  That means anywhere I go, I can access my source code, photos, videos, audio, docs.
